Description

Technical Field

[0001] The utility model relates to the technical field of municipal heating pipeline engineering construction, in particular to an auxiliary tool for inserting pipes into top pipes of underground directly buried steam pipelines. Background Art

[0002] Currently, the construction of municipal heating steam pipelines is increasing. To ensure that steam pipelines are not disturbed by the external environment, reduce heat loss and improve safety, steam pipelines are often designed to be laid directly underground. When underground direct-buried steam pipeline lines cross roads and rivers, they are mostly constructed using the top pipe inner pipe method, that is, the top pipe is used as the outer casing, and then the steam pipeline is laid inside the top pipe. The steam pipeline insertion is the core link of the overall construction. At present, steel-jacketed steel insulated pipes are widely used in direct-buried steam pipelines. The outer surface of the steel-jacketed steel insulated pipe has an anti-corrosion and thermal insulation layer. Due to the large volume and mass of the pipeline and the high protection requirements of the anti-corrosion and thermal insulation layers, it is more difficult to insert the steel-jacketed steel insulated pipe into the top pipe casing. There are usually problems such as slow construction speed, difficult quality control, and high safety risks. These problems have become common problems in the construction of underground direct-buried steam pipelines, affecting not only the construction progress efficiency and process quality control, but also the production safety of the entire project.

[0005] The auxiliary tool for threading pipes inside the top pipe of an underground directly buried steam pipeline has the following technical features: it includes a bracket, a roller is provided at the bottom of the bracket, a pad is provided at the top, and a wavy groove is provided on the surface of the pad. The bracket includes an end bracket and a connecting bracket, one end of the end bracket is provided with a connecting rod, and both ends of the connecting bracket are provided with connecting rods. The end bracket is connected to the connecting rod on the connecting bracket through a rotating shaft, and the connected end bracket and the connecting bracket form a slidable bracket assembly.

[0006] Furthermore, the brackets include at least two groups of end brackets and one group of connecting brackets.

[0007] Furthermore, the rollers are directly opposite to the bottom of the pads, and at least two rollers are correspondingly provided under each pad, so that the bracket assembly can slide and move.

[0008] Furthermore, the roller is connected to the bottom of the bracket through an axle.

[0009] Furthermore, a shock-absorbing spring is provided above the roller, and the smoothness of the movement of the roller is improved by changing the compression amount of the shock-absorbing spring.

[0010] Furthermore, the rotating shaft can be used to fasten the connected connecting rods to adjust the angles between the pads so that each pad fits tightly against the pipe, thereby improving the force uniformity and stability of the pipe when it moves.

[0011] Furthermore, the pad is made of wood or rubber.

[0012] Furthermore, the connecting rod is made of channel steel or aluminum alloy.

[0013] Compared with the existing technology, the utility model provides an auxiliary tool for inserting pipes into underground directly buried steam pipelines, which has the following beneficial effects:

[0014] This auxiliary tool for underground direct-buried steam pipe jacking and threading features a simple structure, strong functionality, wide applicability, and low operational difficulty. The roller mechanism within the tool significantly increases the speed of threading the steam pipe within the jacking casing. The pad within the tool supports and secures the pipe during threading, preventing damage and displacement of the anti-corrosion and insulation layers on the pipe surface due to external friction. This tool effectively improves the safety and quality of threading the steam pipe within the jacking casing. This auxiliary tool can be widely used in all types of underground direct-buried steam pipe jacking and threading construction, demonstrating its significant application value.
